自动打铃系统 附带时钟 定时打铃 整点打铃

基于8B10B的编解码模块的设计，使用verilog HDL语言，具有实用价值。(8B10B encoder)

FPGA的经典例程，可以进行移植和借鉴使用(FPGA' s classic routines, can be transplanted and learn to use)

一个具有“百分秒，秒，分”计时功能的数字跑表，可以实现一个小时以内的精确至百分之一秒的计时。 数字跑表的显示读者可以通过编写数码管显示程序来实现，本训练只给出数字跑表的实现过程。 读者还可以通过增加小时的计时功能，实现完整的跑表功能。-A " percentage of seconds, seconds, minutes," digital stopwatch timer can be achieved within an hour of precision to the hundredth of a second time. Digital stopwatch readers can display the digital display through the preparation of procedures to achieve, given the training is only the realization of the process of digital stopwatch. Readers can also function to increase hours of time to achieve full stopwatch function.
